Product Introduction

Overview

The ADM1066 Super Sequencer® from Analog Devices Inc. is a highly configurable supervisory and sequencing device designed to provide a comprehensive solution for supply monitoring and sequencing in multiple-supply systems. This single-chip device integrates a range of functionalities, including supply fault detection, sequencing, and margining control, along with auxiliary ADC inputs and DAC outputs. It is particularly useful in complex systems requiring precise voltage monitoring and control, such as servers, routers, and multivoltage system line cards.

Key Features

  • Complete supervisory and sequencing solution for up to 10 supplies with supply fault detectors offering <0.5% accuracy at 25°C and <1.0% accuracy across all voltages and temperatures.
  • Five selectable input attenuators for supervising supplies up to 14.4 V on VH and 6 V on VP1 to VP4.
  • Five dual-function inputs (VX1 to VX5) that can be used as high impedance inputs to supply fault detectors or general-purpose logic inputs.
  • Ten programmable driver outputs (PDO1 to PDO10) with open-collector or push/pull configurations.
  • Integrated 12-bit ADC and six 8-bit voltage output DACs for margining control and supply adjustment.
  • Support for closed-loop and open-loop supply margining with minimal external components.

Applications

  • Servers and routers: For complex power supply monitoring and sequencing in high-reliability systems.
  • Multivoltage system line cards: To manage multiple supply voltages in a single card.
  • DSP/FPGA supply sequencing: Ensuring proper power-up and power-down sequences for digital signal processors and field-programmable gate arrays.
  • In-circuit testing of margined supplies: For production testing to verify board functionality and adjust supply voltages as needed).
